1. Are we, as some might say, motivated by a desire to save our off-spring?
I think it is true that in our innate nature, we do have desire to protect our offspring, and live on to create one. It is true that we struggle to survive in order to protect the offspring. Beyond self interest and self respect, people have desire to protect others other than themselves.
2. Must there always be some sort of intrinsic reward for doing good?
Yes, people instinctively create the image of being awarded or re-imaged by the person they helped.

3. Mr. Otis once said, "That having integrity is doing the right thing when no one is watching." If this is so, and no one knows when we have done good, would you still do good?
Yes, this is a matter of conscience. Even though there is no one to award your see you, people still create image of their own goodness and moral. Even though they don't get awarded by anyone else, they get morally mature through this.
4. "Delayed reciprocal altruism", seems like a gamble - back to game theory, any way. Does this seem to make sense to you. That is that we act out of a desire to have what we have done being done to us?

5. Are we ever being truly "selfless" when committing an act of altruism?
No, I think we are always motivated by some kind of award in every "selfless" action. We always have a hidden motivation no matter what we do. There can't be an action without a motivation or reason.
